Bitcoin investment is best suited for long-term investment only, because Bitcoin has been in the market for a long time. To sustain your Bitcoin investment, you must have a plan, because emergency funds play a very important role in making your investment long-term. And you can change your bad habits to make your investment strong and grow your money, because the more you change your bad habits, the more you will be able to accumulate money.
And your investment will have a huge post at the end of the year because if you invest according to the DCA method, it will be easier for you to invest the most.
I dont want you to get things all wrong in investing. From your income, after you have handle other expenses. You first set aside your discretionary income, from which you will invest in Bitcoin. For people who have other habits they can do whatever they want with the remaining discretionary income. As much as the percentage meant for investing has been invested already whether they change their habit or not doesn't change anything. Of course, in some ways limiting some habits can help them grow their investment faster because there will be more percentage that can be invested with but it is not a criteria to a successful investment. What is more important is discipline, investing first and staying consistent.
